The LM3914 is an integrated circuit (IC), designed by National Semiconductor in 1980, used to operate displays that visually show the magnitude of an analog signal. It can drive up to 10 LEDs, LCDs, or vacuum fluorescent displays on its outputs. The linear scaling of the output thresholds makes the device usable, for example, as a voltmeter. In the basic configuration it provides a ten step. A single LM3914 can drive up to 10 LEDs, LCDs, or vacuum fluorescent displays on its outputs. The output threshold linear scaling will make the apparatus functional like a voltmeter. In the basic pattern, it gives a 10 step scale which is flexible to over hundred sections with additional LM series integrated circuits in series 12 Volt Car Battery Meter - A 10 LED calibrated voltmeter from 11-15 volts, needs no extra battery. . .

Two or three mor The LM3914 has the ability to be cascaded in dot mode so that displays bigger than 10 units can be created. It is not possible to terminate the chain (i.e., make a 15-unit display) in any less than multiples of 10. This means that you can produce a display with twenty, thirty, or even one hundred units. Note, however, that the input range is still 0-12V across all stages, so if you did cascade. A battery monitor built ON THE LM3914.

Connect an input voltage of 12.65 volt between the positive and negative poles and adjust the 10K trimmer potentiometer until Led 10 lights up. Lower the voltage and in sequence all other Led's will light up. Check that Led.

National Semiconductor (Texas Instruments) LM3914, similar circuit is often found in the voltmeter/current meter displaying the brightness of microscope lamp house, LED bar graph like in the Olympus BH-2 and I am not sure about the Olympus BX series. The newer microscopes did away with this LED bar graph denoting lamp house light bulb brightness. My Olympus CX31RBSF does not have this LED bar.

Mas aqui discutimos apenas os recursos que nos ajudam na construção do VOLTMETER. O LM3914 é um voltímetro de 10 estágios, o que significa que mostra variações no modo de 10 bits. O chip detecta a tensão de entrada de medição como um parâmetro e a compara com a referência. Digamos que escolhemos uma referência de V, agora, sempre que a tensão de entrada de medição. (multisim|lm3914) - Suche im Elektroforum - - Elektronik und Elektround dazu die Simulation mit den echten Bauteilen aufbauen. Dazu habe ich den MOSFET durch den IRLIZ44NPbF ersetzt, heisst, das Spice Modell ins Multisim eingefügt. Nur schaltet dieser bei der Simulation nicht mehr ab, und der ganze Aufbau funktioniert nicht
